Reproduisez l’échec dans l’image Docker ruby:2.7.4 en utilisant la configuration unprivileged-user et la commande d’installation de net-imap. Commencez par la sortie d’installation de ext/digest et install_headers.rb, et examinez le issue #14 de ruby/digest indiqué. C’est terminé lorsque net-imap et sa dépendance digest s’installent correctement sans permissions élevées.

Description

This is similar to #24, which failed due to io-wait. In this case https://github.com/ruby/digest/issues/14 prevents installation unless the user has access to update the header install location.

some initial setup to create an unpriviledged user:

$ docker run --rm -it ruby:2.7.4 bash
root@d216e60e0a0c:/# useradd --create-home --shell /bin/bash --user-group user
root@d216e60e0a0c:/# su - user
user@d216e60e0a0c:~$ export GEM_HOME="$HOME/gems/$RUBY_MAJOR"
user@d216e60e0a0c:~$ export GEM_PATH="${GEM_HOME}:${GEM_PATH}"

Now, to prove that the user can install other gems and can compile extensions:

user@d216e60e0a0c:~$ gem install json
Fetching json-2.6.1.gem
Building native extensions. This could take a while...
Successfully installed json-2.6.1
1 gem installed

However, net-imap cannot be installed.

user@d216e60e0a0c:~$ gem install net-imap

Fetching io-wait-0.2.1.gem

And the latest pre-release doesn't fix the issue either:
